Actually, the 5.7 6-speed with 18" wheels comes with the 3.73 gears, and the 5.7 6-speed with 20" wheels comes with 3.92 gears.
Just bought the Mrs a Chrysler Aspen 2009 and I threw a Hemi in it. She picks it up in about 2 weeks, early Xmas. We'll see how it does. Maybe I will get lucky too?!
Correcto..............and the 6 spd SRT8 comes with 3.92 std........and both the 3.73 & 3.92 are LSD rears...not the electronic poop....
I hope you do get lucky ... but I didn't ... no LUCK involved here!! I ran 13.5xx three different times, 13.6xx and 13.7xx a handful more. Yes! Since the SRT has the 20" wheels, they get the "better" gears, too. It should be interesting to see how all these different options run!
